IMPRCVEMENT IN TURBINE WATER-WHEELS.

The Schedule referred to in these Letters Patent and making part of the sama.

To all whom t may conce/m Be itv known that I, J AMES MARTIN, of Elorencc, in the couutyLof Lauderdale, in the State of Alabama,

`have invented a new and .useful Improvementin Tur.

bine Water-Wheels;l and I do herebydec-lare that -the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a side sectional view of my invention, taken in the line x x, g. 2.

Figure 2 is a horizontal section of the saine, taken in the line` y y, fig. 1.

Similar letters of reference indicate like parts.

This invention relates to a new and useful improvement in turbine Water-wheels, and has for its object the obtaining, in a more perfect 'manner than hitherto, power from the percussive and reacting force of the Water. f

In the accompanying sheet of drawings- A represents tbe scroll, in which the wheel is fitted and works, said scroll having a horizontal position, and progided with two or more inlet-"passages, B, as shown in g. 2. v l

The wheel G is composed of two annular plates, a a', placed one above the other at a lsuitable distance, the space between being closed, at the inner sides of the plates a. a, by a lining, b.

The buckets D are between the plates a a, and are composed of curved boxes, gradually decreasing in width from one end to the other, and divided into two equal page, c, by a V-shaped partition, d, as shown clearly in g. l

The spaces between the parte c c, at the wide ends of the buckets, are -made concave, as shown at e ie lig. 2.

The plates a a of the wheel are flush with tnc top and bottom ofthe scroll A, and the outer edges of thi: buckets, attheir widest ends, are in line with the ouscroll, being between the outersides of the buckets and the exterior of the scroll.

. From the above description, it will be seen that the water, as it passes through the wheel, first acts byimpact against the concave ends e of the buckets, and then passes through the inclined parts c c, and is discharged at the top `and bottom of the wheel in equal volume.

pass down through the cent-re of the wheel, between its arms g.
